STREET OR STATION INDICATOR.

Specification of Letters Patent.

Application filed May 19, 1913. Serial No. 768,462.

To all whom it may concern.

Be it known that we JONATHAN D. HAR- V131 and HENRY L. GOODWIN, citizensof the United States, residing at Minneapolis, in; the county ofHennepin and State of Minnesota, have invented certain new and usefulImprovements in Street or Station Indicators; and we do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable; others skilled in the art to which itapper- 12 affords means for limiting the extreme tains to make and usethe same.

Our lnvention has for its obgect to provide a simple and highlyefficient street and Y statlon' indicator, and to such ends, gen-Qorally stated, the invention conslsts of the novel devices andcombinations of devices hereinafter described and defined 1n the claims.

dicate like parts throughout the severalf views.

Referring to the drawings :Figures 1 and 2 are similar views in sideelevation showing the improved indicator, some parts being broken awayand illustrating the different positions of certain of the parts; Fig.

3 isa.horizontal section taken on the line 00 m on Fig. 5; Fig. 4 is avertical section taken approximately on the line w m on Fig. 5, someparts being broken away; Fig. 5 is a front elevation of the device withsome parts broken away; Fig. 6 is a vertical section taken on the line ww on Fig. 5; Fig. 7 is a section taken on the line m w on Fig. 5; andFig. 8 is a section taken on the line a a on Fig. 5.

Nearly all of the parts of the mechanism are located within a suitablecasing made up, as shown, of a box-like body section 1 and removablesection 2. The box section 1 is provided with parallel longitudinallyextended inside bearing flanges 3, in which the shafts of four rollers4, 5, 6 and T are journaled. The roller 4 is the feed roller proper andits shaft 4 is provided with a rigidly secured ratchet wheel 8,preferably having square notches. The roller 5 is a relatively smallidle or presser roller, and its shaft 5 is journaled in a bearing fork 9and in longitudinally extended guide strips 10, which latter are rigidlysecured on the bearing flanges 3, so that the said roller 5 is free tomove toward and from the feed roller 4. Both of the rollers 4 and 5 arepreferably provided with pliable facings, preferably of rubber to givethe same better driving friction on the wide faced indicator ribbon 11,which is arranged to run between the same. The yoke 9 is provided with astem 12, which, as shown, works through a suitable bushing 13 set intoone wall of the. case 1. A coiled spring 14 on the stem 12 yieldinglypresses the roller 5 toward the roller 4 and against the ribbon 11. Anut 15 on the outer end of the stem inward movement of the roller 5.

The ln'dlcator ribbon 11, upon which the names of the streets orstations are to be printed in a manner well understood, is attached atone end to the'roller 7, and at its other end to the roller 6., Theshaft 6 of the roller 6 and the shaft '7 of the roller 7 at In theaccompanying drawings which j illustrate the invention, like charactersin:

opposite sides of the case, are provided with spur pinions 16 that meshwith spur gears 17, which latter are loose on spindles 18 rigidlyanchored to the adjacent bearing flanges 3 and sides of the case 1.Helical springs 19 of the clock spring type, are anchored at their innerends to the fixed spindles 18, and at their outer ends are attached tostuds or lateral projections 20 on the respective loose gears 17. One ofthe springs 19 exerts a force in the direction tending to cause theroller 6 to wind up the indicator ribbon 11 thereon, and the otherspring 19 exerts a force in a reverse direction tending to cause theroller 7 to wind up the said indicator ribbon thereon. The said springs19, therefore, yieldingly oppose each other and take up slack in theindicator ribbon and keep as much ribbon wound on the one roller or theother, as permitted by movements of the feed roller 4. The said feedroller 4, therefore, may have a constant or unvarying step by stepmovement, so that the street or station indications on the ribbon may beevenly spaced and will not be afiected by the varying diameter of theribbon rolls on the rollers 6 and 7 Also, these clock springs may bemade long enough to take up and let out a ribbon long enough for thelongest route traveled by any ordinary street car or train.

The street or station indications on the ribbon 11 are, in succession,presented in front of asight opening 21 in the front case, which sightopening is preferably covered by glass, to keep the case dust tight,

may be imparted to the feed roller l either automatically, or at will,by a motorman, conductor, or other person. The means shown is designedto be operated by the latter noted way and comprises a vibratory lever22 pivotally mounted on the shaft r of the feed roller, and providedwith a double acting reversible driving pawl 23 for engagement with theratchet wheel 8.

The numeral 24: indicates a shittable anchor or base of re-action forcoiled springs and 26 on the one side, and springs 25 and 26 on theother side. The springs 25 and 25 are attached to the slide at and tothe lever 22 while the springs 26 and 26 are attached to said slide andto the revcrsible pawl 23. This slide 24: is, as shown, provided with along slot that works on pins 27 in one side of the case section 1. Alink 28 connects one end of the slide 2% to a reversing lever 29, whichis pivotally inounted on the outside of the case, the case beingprovided with a slot through which the said link 28 is adapted to be setinto engagement with either of two notches 30 formed in a latch plate31, secured on one side of the case, as best shown in Fig. 5. The freeend of the pawl-equipped lever 22 through a segmental slot 32 in thecase (se particularly Figs. 3, l and 7). The free outer end of saidlever 2 is attached to one end of a cord or operating cable 33 which ispassed between guide sheaves 34 on one end, and over a guide sheave 35on the other end of a shifting lever 36 that is intermediately pivotedto the case and is connected by a link 37 to the reversing lever 29.When the reversing lever 29, shifting guide lever 36 and spring anchor24 are adjusted, as best shown in Figs. 2 and 7, and the operating cable33 is then pulled and released, the feed roller 4 will be positivelyrotated in the direction of the arrow marked on the ratchet wheel 8 inFig. 7 At this time, it will be noted that the springs 25 and 26 areslack, and hence, thrown out of action, while the spring 25 tends topull the lever 22 toward the left and the spring 26 yieldingly holds theright hand end of the dog 23 in action on the ratchet wheel 8. When thereverse lever 29 is moved to the right and set into engagement with theother notch 30 of the latch plate 31, the spring anchor or slide 24 willbe moved toward the right and thereby throw the springs 25 and 26 intoaction, and give slack to the springs 25 and 26, and thereby throw thelatter out of action. Under this reversecondition, a pull and release ofthe operating cable 33 will cause the feed roller 4 to be rotated injust the reverse direction from that indicated by the arrow marked onFig. 7. This same shifting movement of the reversing lever 29 throws theshifting guide lever 36 from the position shown in Fig. 2 into theposition.

works I shown in Fig. 1, so that under both conditions or adjustmentsabove described, the said cable will always pull the lever 22 againstthe tension of the spring 25 or 25, as the case may be. Obviously, thespring 26 when under tension, renders operative the right hand end ofthe reversible pawl 23, while the spring 26 when put under ten sion,throws the left hand end of said pawl into action on the ratchet wheel8. It should be here noted that the friction produced by the pressure ofthe roller 5 against or toward the feed roller 4-. and against theindicator ribbon 11, is sufficient to hold the said ribbon in anyposition in which it may be setagainst the tension of the opposingsprings 19. Hence, movements of the said indicator ribbon are dependententirely upon movements of the said feed roller.

Fig. 4t indicates a gong which is automatically operated to indicateeach complete step of movement of the feed roller 4. This gong comprisesa small bell 38 secured to a suitable standard 39 on the case 1, andsubject to a hammer 4-0 pivoted to a rock shaft 4L1 suitably mounted onthe case and provided with an arm 42 that works on the pe riphery of theratchet wheel 8. The hammer 4L0 will strike the bell 38 whenever thefree end of the arm 42 falls into one of the notches of the said ratchetwheel 8, which action takes place at the completion of the full movementof the said feed roller. Hence, anything short of a complete or properfull movement of the feed roller will not operate the gong.
